Final lacquering of sheet-, bulk- or resin transfer-molded, fiber-reinforced plastics part, used as vehicle bodywork part, e.g. in final car assembly, involves applying adhesive, pressing lacquer film onto part in mold and thermal cure

摘要

Final lacquering of fiber-reinforced plastics part made by an SMC, BMC or RTM (sheet or bulk molding compound or resin transfer molding) process comprises coating part with adhesive; placing molding and a lacquer film in a press molding tool; heating film to or above glass transition temperature of its polymer component; drawing lacquer film onto surface of part; pressing film onto part by excess gas pressure in tool; and thermal cure of adhesive. An independent claim is also included for fiber-reinforced plastics parts made by this process, with lacquer film bonded directly to its surface, such that the depth of roughness of the lacquered surface is under 1 mu m and the fiber structure of the part is no longer visible under the lacquer.
